It depends on the angle between them.

Thank you very much

If the only vectors are A=3.00m and B=3.00, vector -b would be -3.00, right? So wouldn't the distance be 0m? Or is this totally wrong?

Thank you

A vector has magnitude and direction, to talk about a vector of just 3m is meaningless.
If they were in the same line then A - B would be zero.
If they were at right angles the distance would be 4.2m
